True/ False
The gravitational force only acts btwn very massive objects
F
Doubling the distance between two objects halves the gravitational force between them.
F (1/4 Fgrav bc gmm/2r^2)
If object is placed 2 earth radii above earth, then 1/4 Fgrav
F (2 radii ABOVE earth, so 3 total = 3r^2 = 1/9 Fgrav)
Accel of g depends on mass of object
F (Wf = m*g- two separate things)
Incr mass of Object = incr g of Object?
F (changes Wf but not g)
Gravitational force btwn 2 objects is independent of smaller mass
F (dependent on both masses)
2x mass of earth and 2x radius = g still = 10 ish m/s ?
F (g= Gm/d^2- dist squared and m isnt- 2m/4r)
The gravitational force btwn an object and and the earth is inversely related to dist btwn object and earths center
F (inversely prop to dist squared)
If A attracts B with X newtons, B also attracts A with X Newtons
T
2x dist = decr g by factor of 4 ?
T (1/4 Fgrav)
Gravitational force acting on object is same as weight of object
T (Fgrav = Wf)
Gravitational force can Always be accurately calculated by mg
T (Fgrav = Wf)
Accel of g depends on mass of earth
T (accel DUE to gravity- Earth's pull)
Accel of g is inversely related to dist btwn the center of earth and center of object
T (ex: more dist = less g)
2x mass of earth (radius same tho), then g = 20 ish m/s ?
T (g = Gm/d^2)
Accel of orbiting object (constant speed) = accel of g at that particular location
T (idk why)
In both Copernican and Keplerian systems, the closer a planet is to the sun, the faster it moves
True
